Discovery Channel Sued Over Lincoln Doc Discovery Channel has plans to air a documentary on Abraham Lincoln this Sunday, but two researchers are trying to put a stop to the broadcast. The documentary titled, Undiscovered: The Lost Lincoln will include an image of the former president that researchers Dr. Jerry Spolar and Dr. Tonny Jill Williamson claim Discovery Channel disclosed, violating their nondisclosure agreement. Discovery claims they didn't know that there were competing claims of ownership of what's said to be the last glass image of Lincoln. The two researchers are looking to have the broadcast of the documentary halted. Do you think that the show will still air on Sunday? Have you ever found a historical item?
